Bell Work Friday 9/161. What did you learn from the sugar lab?2. Which foods had both high starch and high sugar?3. What do you think the body uses proteins for?4. What is a food that is high in protein? Low in protein?5. Are proteins only found in muscles?
What do you call a teenager who plays professional sports?

2. Answers to Cover Page
3. Questions page
4. Data Table
5. Graph
6. Drawings of Brine Shrimp
Predict the Amount of Protein
0 = no protein+ = a little protein++ = medium protein+++ = lots of protein
Predicted Protein
Actual Protein
Chicken Broth
Apple Juice
Milk
Onion Juice
Corn
Potato
Bean
Protein Test• Put about 1cm of each food in a separate test
tube• Use the same order of foods as in the list
• Put on GOGGLES and leave on until you are done with clean up!
• Add 10 drops of Biuret’s Solution to each • Mix each tube for 30 sec• Record the color change (0 to +++)
Protein Lab Cleanup1. Pour out test tubes in blue and red bin2. Scrub and rinse test tubes3. Put in test tube rack upside down to dry4. Wipe off table and wipe out sink if needed
General CleanupClean up has been good so far, but we can do betterYour station should look exactly like it did when you found it• Please keep the back sink clean• If you see water on a counter, please just grab a paper
towel and wipe it up, Mr. Horton will love you forever and ever.
• Lose points for messy lab stations
Protein Lab Questions
1. What color did the foods with protein turn?2. Which of the foods in this experiment would you want
to eat to build muscle?3. Which food(s) had the least protein?
*When you finish, turn in the starch lab, sugar lab, and protein lab stapled together with your:
***FIRST NAME, LAST NAME, PERIOD in the top right corner
• Proteins– Made up of amino acid building blocks
– 1000’s of functions:• muscle movement• digestive enzymes
• antibodies
– Body structures are made of proteins• Hair, fingernails, muscles, enzymes
• Each kind of protein has a special shape– At first, a long chain of amino acids
• Like pop-bead necklace
– Chain folds up into a unique 3-D shape– Function and shape go together
• 2 examples of “Shape & Function Match”
–A) Hemoglobin• Function
–carry oxygen in blood
• Shape is like a “cage”–Oxygen fits perfectly inside cage
• Muscle Protein– Function
• Contract & relax to cause movement
– Shape • long & thin with “teeth” like combs• Teeth grip & ungrip like Velcro• Slide to get longer & shorter
More Overlap = shorter muscle
Less Overlap = longer muscle
• Could hemoglobin do the job of muscle protein?
• Could muscle protein do the job of hemoglobin?
WHY NOT?
Q & A: Proteins1) What are the building blocks for proteins?2) Proteins start out __________________ & end up
___________________________.3) Name 2 functions of proteins.4) Name 2 examples of structures made of proteins.5) Explain how “Shape Matches Function” for
hemoglobin.6) Explain how “Shape Matches Function” for muscle
proteins.7) How can proteins have so many different functions
in the body?
Don’t write the question but answer in complete sentences IYOW.
